I don't have all the answers about what it'll take to adapt the T-5 to your truck, but looking at the motor you're running, I don't think it'd take too many full power runs before you had a box of neutrals. T-5s aren't the strongest transmissions around. If you really want a 5-speed, a Tremec 3550 is a great choice and can handle a lot more power than a T-5. I've had both and I prefer the Tremec by a LONG ways over the T-5.
The other choice might be a T-56, but I have no experience with them at all.
